Auto merge of #4447 - lucaskolstad:proc-macro-crates-host-deps-linkage, r=alexcrichton
Add host dependency path via -L for cargo_test.
Proc-macro crates' dependencies in the host dependency directory cannot
be found when running `cargo test` with the `--target {target}` flag
set as reported in #4224. This adds the host dependency directory to the
search path to find those missing dependencies with -L when building tests
and adds a test case that fails before and passes after this patch.
A new function `find_host_deps(..)` is added to accomplish this which can
determine the path of the host dependencies directory from within
`run_doc_tests(..)` where the missing library search path is needed.

**Concerns**
The test case seems to require a non-local crate from crates.io to example the failure before this patch. Couldn't make it fail with simply another local subcrate, but if others think it's possible that'd be great. This means that during tests for the cargo project itself that this test case actually downloads and compiles a crate, which I don't think any other tests do and is obviously not ideal and is perhaps even unacceptable. I've used the base64 crate pretty arbitrarily, but which crate it is really doesn't matter to test the case's content. So if anyone knows a tiny or empty crate on crates.io to use instead that'd speed this up and if someone can figure out how to make it fail before this patch is applied without downloading an external crate that would help as well.
Also, I'm not 100% confident about the `find_host_deps(..)` style and whether it's the best way to find the host dependencies directory with just the `TestOptions` and `Compilation` structs available since I'm new to this project. Any comments are appreciated.

Replace plugins_dylib_path with host_deps_output.
The plugins_dylib_path field on Compilation is removed because it is
identical to host_deps_output, it is only used in one easily replaced
location, and because host_deps_output is a more general name that
includes its new usage location in cargo_test.rs as well while better
matching the corresponding deps_output field.
Also de-indents erroneously indented lines in a test case.

Add infrastructure for nightly features and flags
This PR starts adding infrastructure in Cargo for nightly features and nightly flags. The current design looks like:
* There's a new `package.cargo-features` manifest key which accepts an array of strings. This array of strings is the list of enabled Cargo features for that crate.
* A new suite of flags behind `-Z`, like the compiler, are accepted on the command line for all commands.
* Features and unstable flags in Cargo are required to be used on Cargo's nightly channel, which is the same as Rust's nightly channel.
* Features and unstable flags cannot be used on the stable/beta channels of Rust/Cargo.
* Crates which enable features in their manifest are disallowed from being published to crates.io
The motivation behind this support is unblock a number of efforts in Cargo by allowing them to safely get implemented behind a nightly feature gate. Once behind a feature gate they can iterate in-tree without having to worry about "insta stability" and we can also get valuable usage feedback about upstream users.

Expose `Target` and `Unit` params to appropriate `Executor` callbacks
This effectively does only two things:
* Pass existing `&Unit` to `init()`
* Pass existing `&Target` to `exec()`s
Also updated doc comments slightly.
The `init()` is called for every `Work` preparation by `rustc()` and since it's not called once (not sure if intended?), it'd be good to include more information for which `Unit` the `rustc` process invocation has been initially prepared (I think more importantly it shows that `init()` is called many times for many targets).
Additionally, it'd be good to know about `Unit` compiled in the `exec()` callbacks in more structured manner (so the user doesn't have to parse the `ProcessBuilder` arguments and/or make certain assumptions) and since `target` was already cloned and moved into the closure, it was only a matter of exposing it.
I think it'd be ideal to provide all the necessary information to recreate a `Unit` but with a static lifetime needed for the closure, however this would mean cloning more data per-target ([`Kind`](https://github.com/rust-lang/cargo/blob/master/src/cargo/ops/cargo_rustc/mod.rs#L41) should be basically free, however not sure if cloning [`Profile`](https://github.com/rust-lang/cargo/blob/master/src/cargo/core/manifest.rs#L151) is acceptable). With this, `Executor` users could query `Context` more easily (e.g. to get a unit dep graph! :smile:), as the API accepts `Unit`s in many places.

Required dependencies are not features
Also, while I was at it, I fixed an error message which complained about something not being an optional dependency, when really what mattered was that it was not a dependency at all.
I made a bunch of guesses about how things work. These guesses ended up as comments in the commit (so hopefully, the next reader of these files has to guess less). I am not totally certain these comments are all correct, so please yell if not. :)
In particular, for resolve_features, I observed that dependencies get compiled even when they are not returned from that function. But judging from how the function used to behave, it actually returns all dependencies, even those that have nothing to do with any features. (Making the name rather misleading, TBH...)

[sources/path] Support leading slash in glob patterns
Background: https://github.com/rust-lang/cargo/issues/4268
This diff takes us to **Stage 1.1** of the migration plan by allowing
glob patterns to include a leading slash, so that glob patterns can be
updated, if needed, to start with a slash, closer to the future behavior
with gitignore-like matching.
Why is this stage needed?
It's common to have `package.include` set like this:
```
include = ["src/**"]
```
In old interpretation, this would only include all files under the `src`
directory under the package root. With the new interpretation, this

directly under the package root.
After this patch, package owners can start marking glob patters with a
leading slash to fix the warning thrown, if any.
One thing to notice here is that there are no extra matchings, but, if
a manifest has already a pattern with a leading slash, this would
silently start matching it with the paths. I believe this is fine, since
the old behavior would have been for the pattern to not match anything,
therefore the item was useless.

Auto merge of #3611 - tylerwhall:stable-metadata, r=alexcrichton
Stable metadata hashes across workspaces
Currently a crate from a path source will have its metadata hash incorporate its absolute path on the system where it is built. This always impacts top-level crates, which means that compiling the same source with the same dependencies and compiler version will generate libraries with symbol names that vary depending on where the workspace resides on the machine.
This is hopefully a general solution to the hack we've used in meta-rust to make dynamic linking reliable.
meta-rust/meta-rust@
0e6cf94
For paths inside the Cargo workspace, hash their SourceId relative to the root of the workspace. Paths outside of a workspace are still hashed as absolute.
This stability is important for reproducible builds as part of a larger build system that employs caching of artifacts, such as OpenEmbedded.
OpenEmbedded tightly controls all inputs to a build and its caching assumes that an equivalent artifact will always result from the same set of inputs. The workspace path is not considered to be an influential input, however.
For example, if Cargo is used to compile libstd shared objects which downstream crates link to dynamically, it must be possible to rebuild libstd given the same inputs and produce a library that is at least link-compatible with the original. If the build system happens to cache the downstream crates but needs to rebuild libstd and the user happens to be building in a different workspace path, currently Cargo will generate a library incompatible with the original and the downstream executables will fail at runtime on the target.

In the current documentation, there are many places with language that

With the new workspace features, this is far from true now, and the
inaccurate language makes it difficault for newbies or developers

[sources/path] Support leading slash in glob patterns
Background: https://github.com/rust-lang/cargo/issues/4268
This diff takes us to **Stage 1.1** of the migration plan by allowing
glob patterns to include a leading slash, so that glob patterns can be
updated, if needed, to start with a slash, closer to the future behavior
with gitignore-like matching.
Why is this stage needed?
It's common to have `package.include` set like this:
```
include = ["src/**"]
```
In old interpretation, this would only include all files under the `src`
directory under the package root. With the new interpretation, this
would match any path with some directory called `src`, even if it's not
directly under the package root.
After this patch, package owners can start marking glob patters with a
leading slash to fix the warning thrown, if any.
One thing to notice here is that there are no extra matchings, but, if
a manifest has already a pattern with a leading slash, this would
silently start matching it with the paths. I believe this is fine, since
